A quick refresher course. DRM-free tracks will be available for $1.29, or $.30 more than tracks with Apple's Fair Play copy protection. While the ability to play the files on any device you choose is probably worth the extra cost, the songs will also be encoded at 256kbps, compared with 128kbps for the encrypted $.99 songs.
Apple is also expanding its iTunes U service, making university lectures available to the public for free.
